Abstract
An improvement in a control valve having a body, a body interior portion and plural exterior ports in communication with the interior portion. The improvement includes a plurality of dovetail-like body slots 'isolated' or spaced from other slots. Each slot intersects an aperture in fluid communication with the body interior portion. A complementarily shaped, friction-retained slide-by plate is in each slot and at least one plate includes a port in fluid communication with the slot aperture. Each plate slides for removal without disturbing any other plate. A plate may be a blind closure plate, a ported plate tapped with any of several thread sizes or a 'back-to-back' interface plate for supportively mounting valve bodies in tandem. A control valve system including a slotted valve body and an assortment of plates of various types provides substantially 'universal' porting between the body and another valve body and/or one or more separate control components.
